14 MARWELL Price Paid vs. HPI Average

The below graph shows the average detached house price in the Sevenoaks local authority area over time, sourced from the HPI. The two 14 MARWELL sales from March 1996 and October 2019 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the March 1996 sale was for 6% above the HPI. So the extrapolation line tracks at 6% above the HPI over time, until the October 2019 sale, where it falls to 6% below the HPI. The line then continues to track at 6% below the HPI.

What might 14 MARWELL be worth now?

14 MARWELL might now be worth an estimated £889,358.

This is based on house price inflation of 16.6%, between October 2019 and December 2024, for detached houses, in the Sevenoaks local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 16.6% inflationary increase is applied to the most recent sale price for 14 MARWELL of £762,500 on 4th October 2019. For the value to have increased from £762,500 to £889,358 over the four years and ten months to December 2024, the following assumptions must hold true:

• The value of 14 MARWELL has moved in line with the HPI for detached houses in the Sevenoaks local authority area.
• The October 2019 sale price of £762,500 represented a fair market value for the property.
• The size, condition, and specification of 14 MARWELL has not materially changed since October 2019.
